ABSTRACT

Studies on the adsorption capacities of bamboo-based activated charcoal (BBAC) and bamboo dust (BD) onto lead (11) and Cadmium (11) ions were carried out. Effect of various process parameters has been investigated by following the batch adsorption technique. Results revealed that the percentage removal of Pb2+ and Cd2+ from aqueous solutions increased with increase in particle size of the adsorbents (0.3 mm - 0.6 mm). As initial pH of the aqueous solution was increased, the percentage removal of the metal ions increased optimally. Temperature variation showed percentage removal increasing between 303K (30°C) and 323 (50°C) and decreased at 70°C. At varied contact time, the percentage removal of the metal ions increased and maintained a constant adsorption at 90 min. percentage removal of lead (11) and Cadmium (11) decreased with increase in initial metal ions concentrations of 20 mg/L, 80 mg/L. adsorption capacity trend for the various parameters studied with BBAC and BD showed Pb2+ > Cd2+. The adsorption data were modeled with the Van’t Hoff thermodynamic equation, Pseudo-first and second order equations, Langmuir and Freundlich isotherms and the models were found to be very applicable. Negative values of AG°ads depicted the feasibility and spontaneous nature of the adsorption process while AH°ads indicated the exothermic nature of the process. Adsorption of lead (11) and Cd (11) ions by bamboo-based activated charcoal (BBAC) and bamboo dust (BD) was found to be favourable and hence could be employed as alternative adsorbents for wastewater/ aqueous solution treatment.
